'consistently-moving' originates from the combination of 'consistent' and 'move', where 'consistent' comes from Latin 'consistere', meaning 'to stand firm', and 'move' from Latin 'movere', meaning 'to move'.

'consistere' transformed into the Old French 'consister', and eventually became the modern English word 'consistent'. 'Movere' transformed into the Old French 'mover', and eventually became the modern English word 'move'.

Initially, 'consistent' meant 'standing firm', but over time it evolved into its current meaning of 'unchanging'. 'Move' has largely retained its original meaning of 'to change position'.
